"I have a lot of spirit for this, for this reason, it's a great experience, I want to see and I want to learn.

"The football is always the same, but if you have an open mind you take. Dortmund were in a bad position but it was unbelievable as they played so well.

'They created five or six chances but didn't score.

"For me it's not important what a manager is doing in a little period, it's about the big period."

Ranieri's reputation took a battering after he lost four and drew one of his five games as Greece boss but the 64-year-old is not bothered by his past despite restoring his reputation at the King Power Stadium.

He added: "For me my reputation is not important, I know I'm an honest man, I am not 'good after I was not good'. It's the right balance. I love my job, I have so much passion.

"Look, in my career - what was important was just four matches (with Greece), what I did before those four matches with Greece was nothing!

"After that it was 'Ranieri is no good... go home'. I was sacked. But then another coach arrived and he was worse and another arrived, he was worse."
